Port address translation (PAT) enables multiple devices on a local network to make outbound connections over the internet using the same gateway address by allocating specific ports to individual sessions. This feature allows effective sharing of a single address for internet access requirements.\n\n* Allocating unique gateway addresses to each workstation (incorrect) is not feasible due to the limitation of only one external address.\n* The Dynamic Host Configuration Protocol (DHCP) (incorrect) is primarily involved with the internal allocation of dynamic addresses to clients in the network, not with external address sharing or internet session management.\n* Standard Network Address Translation (NAT) (incorrect), on its own, translates local addresses to an external address but does not differentiate connections by ports like PAT does, thus it cannot handle simultaneous external accesses individually.
